Installation
============

Pwntools is best supported on 64-bit Ubuntu LTS releases (14.04, 16.04, 18.04, and 20.04).  Most functionality should work on any Posix-like distribution (Debian, Arch, FreeBSD, OSX, etc.).

Prerequisites
-------------

In order to get the most out of ``pwntools``, you should have the
following system libraries installed.

.. toctree::
   :maxdepth: 3
   :glob:

   install/*

Released Version
-----------------

pwntools is available as a ``pip`` package for both Python2 and Python3.

Python3
^^^^^^^

.. code-block:: bash

    $ apt-get update
    $ apt-get install python3 python3-pip python3-dev git libssl-dev libffi-dev build-essential
    $ python3 -m pip install --upgrade pip
    $ python3 -m pip install --upgrade pwntools


Python2 (Deprecated)
^^^^^^^^^^^^^^^^^^^^

NOTE: Pwntools maintainers STRONGLY recommend using Python3 for all future Pwntools-based scripts and projects.

Additionally, due to `pip` dropping support for Python2, a specfic version of `pip` must be installed.

.. code-block:: bash

    $ apt-get update
    $ apt-get install python python-pip python-dev git libssl-dev libffi-dev build-essential
    $ python2 -m pip install --upgrade pip==20.3.4
    $ python2 -m pip install --upgrade pwntools


Command-Line Tools
------------------

When installed with ``sudo`` the above commands will install Pwntools' command-line tools to somewhere like ``/usr/bin``.

However, if you run as an unprivileged user, you may see a warning message that looks like this::

    WARNING: The scripts asm, checksec, common, constgrep, cyclic, debug, disablenx, disasm, 
    elfdiff, elfpatch, errno, hex, main, phd, pwn, pwnstrip, scramble, shellcraft, template, 
    unhex, update and version are installed in '/home/user/.local/bin' which is not on PATH.

Follow the instructions listed and add ``~/.local/bin`` to your ``$PATH`` environment variable.

Development
--------------

If you are hacking on Pwntools locally, you'll want to do something like this:

.. code-block:: bash

    $ git clone https://github.com/Gallopsled/pwntools
    $ pip install --upgrade --editable ./pwntools

.. _Ubuntu: https://launchpad.net/~pwntools/+archive/ubuntu/binutils
